What would you guys feel if they insult Shugo Chara anime? Examples... They say that this anime is childish and illogical. How would you guys feel? If you ask me? I'll be extremely mad cause this anime is awesome!

There's no reason to get extremely upset about someone liking different things than you. Not everyone on the planet is going to agree with you, that's just a given. Exploding with anger at them will not make them any more likely to agree with you. At most, it will drive them further away from what you're 'defending'. Anger only leads to more anger, while kindness only leads to more kindness.
